Vaishnava Samhita. Narasimha Mehta Charitam III. Vol III Book VI Chp 17 Shloka 7

नराणां कृष्णभक्तानां ऋणशेषो न विद्यते  |
मुच्यन्ते लोकवेदाभ्यां कृष्णप्रेमपरायणाः ||

But the Krishna bhaktas do not owe anything to anyone. For, they get liberated from all bonds of dutiful actions as they have Krishna bhakti as their only object in life.
